that show these types of lesions most likely will result in damage to the nerve fibre
layer and affect vision if the lesion size is a substantial size. These cases would be
unsuitable for purchase. Multiple small “bullet holes” lesion through the non tapetal
fundus are consider normal and very common.
Conclusion:
The ocular component of PPE is important and requires a thorough check of the
globe and one needs to ensure that all parts of the globe are examined. No horse is
perfect in every respect and some findings are manageable and the horse may be
visual and functional and could be considered suitable.
